DETAILED DESCRIPTION OF THE INVENTION

The structural features and the effects to be achieved may further beunderstood and appreciated by reference to the presently preferredembodiments together with the detailed description.

First, referring to the FIG. 1, is a structure diagram of a preferredembodiment of the present invention seamless down cloth. The down cloth10 comprises a shell fabric 11, a lining 13, and down (not shown),wherein the down are provided between the shell fabric 11 and the lining13, a plurality of down areas 111 and a plurality of pasted areas 113are spread around the shell fabric 11, the shell fabric 11 is withseamless. The pasting material of the pasted areas can be a PU adhesivefilm or s PU glue, and the pasted areas can be designed as any patterns,such as a line type, a curve type, or a ravine type, therefore, the downcloth 10 will be with various outlooks.

The present invention disclosed a seamless skill that provides severalpasted areas to divide the shell fabric 11 into several down areas 111,and fills proper down into each down area, such that the down will notbe spilled easily from suture, even the down is very slippery, thus, thecloth will be more comfortable and good looking, furthermore, since thecloth is without any sutures and stitches, the water proof can be moreefficiency according to the various functions of the cloth,sequentially, the material of shell fabric 11 can be with functions ofwater proof, wind proof, moisture conductivity, or the combinationthereof, such that can provide the functions of well water proof for thecloth, and since the seamless feature of the cloth can be used forpreventing the air convection that can cause heat flowing away, thecloth will be better on warm keeping. And further, the hem width of theshell fabric 11 is lesser, according to the seamless for the cloth.Especially, the down cloth can be altered to comprise two layers only,which are the shell fabric 11 and the lining 13, instead of the originalthree layers, which are the shell fabric, the lining, and the padding,thus, the weight of the cloth can be reduced efficiently.

Referring to FIG. 2, is a flow chart of a preferred embodiment of thepresent invention seamless down cloth manufacturing method. The methodcomprises the steps of:

-   Step 201, patterning for a designed pattern of a down cloth 10    according to the determined size;-   Step 202, cutting a sample (not shown) provided after patterning;-   Step 203, forming the down cloth 10, designing a pasted pattern (not    shown), cutting the pasted pattern and a shell fabric 11, stacking a    lining 13, the pasted pattern, and the shell fabric 10 in order    according to the pattern, and pasting that;-   Step 204, filling proper down into a plurality of down areas 111    regarding as the required weight for each, that is, much-down filled    will cause the cloth too heavy, on the other hand, less-down filled    will cause the cloth too light and effect the outlook and the warm    keeping; and-   Step 205, sewing at least one accessory 115 on the down cloth 10,    such as zippers, buttons, and so on.

The mentioned way of cutting can be selectively as a manual cutting, apunching cutting, and a laser cutting. Accordingly, the laser cuttingcan be implemented by the process of designing the pasted pattern by thecomputer software, setting the energy and the velocity of the lasercutting machine, and cutting the pasted pattern by the laser cuttingmachine, wherein the energy of that can be set around 90 to 98, thevelocity of that can be set around 12 to 15, consequently, the differentwidths of pasted area 113 material and shell fabric 11 are requireddifferent energy and velocity. The outermost layer of the shell fabric11 is processed with a thinnest long lasting spray-on PU film during themanufacturing of the shell fabric 11, thus, drops will be pushed throughunder certain moist circumstances, the seamless and smoother surface ofthe cloth can be used to alter the water run-off, such that the dropswill be slipped off rapidly, therefore, the water proof function can beprovided according to the down cloth 10 surely. At raining, the downcloth having water proof function can prevent the lost of bodytemperature, furthermore, which is more comfortable for people.

The lining 13, pasted pattern, and the shell fabric 11 are pasted by hotpasting, for example, setting the parameters of the temperature, thepressure, and the pressing period time of a hot pasting machine (notshown), the lining 13, the pasted pattern, and the shell fabric 11 arestacked in order according to the sample and pasted by the hot pastingmachine. Of course, the manufacturer can test the parameters oftemperature, the pressure, and the pressing period time first forobtaining the optimal value to set the parameters of the hot pastingmachine. Sequentially, once the temperature is higher, or the pressingperiod time is longer, the shell fabric 11 will be burned, that is, theshell fabric 11 will be with bad ventilation and effect the function ofwater proof; on the other hand, once the pressing period time isshorter, the temperature is lower, or the pressure is insufficient, theshell fabric 11 and the lining 13 will be pasted insecurely, such thatthe down between the shell fabric 11 and the lining 13 will movetogether since the insecure pasted. Accordingly, the function of warmkeeping for the cloth will be affected.

Finally, the seamless down cloth 10 manufactured from the perviousmentioned methods can prevent the attrition of stitches and sutures inaccordance the laser cutting, hot pasting, and so on. The outlook of thedown cloth 10 is more featly and smoother. Wherein, the material of theshell fabric 11 can be selected with lighter, tender, and morecomfortable, further, the function of that can be selected with waterproof, snow proof, wind proof, moisture conductivity, ventilation, oilproof, dirty proof, and so on.
